Re: [PATCH v3 1/6] dma-buf: Remove the signaled bit status check

[Christian König]

Am 09.09.22 um 19:08 schrieb Arvind Yadav:

Remove the signaled bit status check because it is returning
early when the fence is already signaled and
__dma_fence_enable_signaling is checking the status of signaled
bit again.
